To all 'whom it may concern:

Be it known that we, GUsTAvE GAIRE, PAUL GAIRE, and Josnrn GAIRE, citizens of `France, residing at Paterson, 'in the county of Passaic and State of New Jersey, have invented certain new and useful Improve; ments in Machines for Beveling. Round Glass, of which the following is a specifica# tion. Y

This invention embodies improvements in machines designed particularly for the purpose of rinding glass.

The o ject of the invention is to l)rovide a machine of the above ltype .which is constructed for the purpose of beveling round Glass, Ior the like, and in the practical em- -odiment of the inventiony it is aimed to.

secure a structure which is simple, comparatively speaking, and which includes a compact arrangement of parts ada ted to be l adjusted to accommodate work o different sizes and possessing other advantages under actual conditions of service.

For a full understanding of the invention, reference is to be had to the following detail description and to the accompanying drawings, in which* Figure 1 is a side elevation of a machine embodying the essential features of the invention; Fig. 2 isa top plan view; Fig. 3 is a vertical longitudinal sectional view; Fig. 4 is a transverse sectional view taken about on the line lf-4 'of Fig. 1 andlooking in the direction of the arrow; Fig. 5 is a transverse section bringing out more clearly the mounting of the grinding wheel, Fig. G is a detail sectional view, partially broken away, showi mg clearly the work supporting and clamping means and the operating connections for rotatingthework support g Fig. 7 is a fragmentary view of the upper portion of the frame ofthe carriage showing members of the sectional bearing carried thereby; Fig` 8 is a detail view partly in section, bringing out more clearly the mounting of the blocks adjustably mounted on the vertical standards and which support the grinding wheel shaft.

Throughout the following description and on the several figures of the drawings, similar parts are referred to by like reference characters.

Specifically describing the invention the numeral 1 designates the base of the machine upon which are mounted the variousparts ofv I the mechanisms employed for the purposes of theinvention. he base 1 is preferably `from the Grinding wheel 8.

of sdmewhat rectangular form though not necessarily so, and carried by brackets 2 secured to opposite sides of the base are vertical standards 3 which are attached at' the lower ends to the brackets 2 by suitable fastenings,` In eachv of the standards 3 is mounted a block 4 adjustable by means of a 4screws 5, the lower end of which has a' swivelconnection 6 with the block, the screw 5 having a threaded connection with the upper end portion ofthe standard upon which it is mounted Eachlblock 4 carries a horizontal threaded member 7 which passes through the block and has threaded connection -With the latter permitting suitable adjustment. The4 grinding wheel is indicated at 8 and is carried by a shaft 9 upon which is also keyed'or .l

otherwise secured arplulley 1() connected with a drive belt 11'. e opposite ends of the shaft 9 are pointed and received in bearings in the adjacent or inner ends of'the adjnstable threaded members 7, and it will be a arent that the shaft 9 is readily displaceahlh and mounted in adjustable bearings.

Extending longitudinally of the base 1 of. the machine area pair of guide rods 12 which support a carria e 13 mounted for move ment longitudina ly of 'the base toward' and The carriage 13 consists of a rectangular frame secured at its opposite ends to longitudinal bars 14, said bars being carried bydownwardly projecting arms l5 attac-hed to the under sides thereof,

said arms being formed with openings through which the members 12 pass. Two

of the members 15 are secured to each bar 14 and arranged adjacent toa side ofthe base, the arrangement of the members 15 permitting of mere sliding movement thereof along the guide rods 12 when thecarria e 13v is being moved lengthwise of the mac e. The frame of the carriage 13 consists of up er and lower plates 13HL and 13b respective y, and mounted between said vertical shaft 16 having a pi ley 17 attached thereto intermediate of its ends, a 'drive belt mounted. about a shalt 20 supported. in suitupper plate 13 of the frame of the carrie e 13, the said bearing being shown more 'clear y plates 1s a shortl by the.V

.18 passing about said pulley.' VThe drive belt, I 1S also passes around a drive pulley 19 in Fig. 7 of the drawings. The lower end of the shaft 16 is also mounted on an adjustable member 23 provided with a suitable bearing for said shaft. At its upper end portion the pulley 19.

shaft 16 is threaded so as to readily connect with the Work support or head 24 which is formed with a threaded recess adapted to receive the upper end of the shaft 16. The work support 24 is thus securely connected. with the shaft 16 and is rotatable with said shaft whenthe machine is in operation, the shaft being driven by the shaft 18 from the On its upper side the work support 24, which virtually comprises the detachable head on the shaft 16, is provided with a covering 25 of some soft material which is adapted to frietionally engage the work or glass but will prevent scratching or injury to the same in anv obvious manner, when the work is clamped or held. against the head or support 24. Between the head or Work sup ort 24 and a shoulder near the upper end o the shaft 16 is supported a pan 26 which exten-ds over those parts of the machine adjacent to and beneath the grinding wheel 8 and prevents the water or other foreign matter which is splashed or thrown outving the parts aforesaid.

wardly in the grinding operation from injur- The pan 26 mclmes downwardly at one end so as to extend be Aneath the grinding wheel 8 as shown most lclearly in the drawings.

In order to i'irmly hold the work in place as it is operated upon by the grinding wheel 8 it is contemplated to provide peculiar clamping means. Said means consists of a shaft 27 arranged transverselyof the machine and mounted in bearings at the upper portions of vertical brackets 28 carried Aby the bars 13. Secured to the shaft 27 is a clampingmember or arm 29 one end of which is formed with a downwardly extending point or pro- The norvmal tension. of the spring 34 is such as to cause the projection 3() to firmly engage and hold the piece of glass or other work upon the work support, 24, and by 'reason of the parent that the-member 30 thereof virtual y performs the'funcfion ofa pivot bearing permitting of proper rotation ol' the glass carried by the ,support 24 and. arranged so that its edge will be ground or beveled prooerlv by the wheel 18 coming into contact there- With. A handle. 35 is connected with the the handle the clamping arm 29 may be raised from the Work, whichy is indicated at 37, when it is desired to remove the work or position the glass roperly with reference to the grinding whee Asuitable pi )e is used to convey water to the grinding w reel 8, as shown in Fig. 1.

ln order to facilitate the adjustment of the.

from the grinding wheel 8 it is contemplated to provide a feed screw 39 which isl swivelly connected with an end of the bas.. 1 of the machine and is provided at its outer end with .a handle 40. The screw 39 passes through a pendent arm or arms 41 carried by the lower plate 13b of the carriage 13, and by turning the screw 39 'it will be apparent that the carriage may bc readily moved longitudinally of the base 1 and its position suitably adjusted with reference to the grinding wheel 8. The spring 42 .mounted upon the Irod 43 suitably carried by the base of the frame bears at one end against the downwardly projecting eX- tension 44 of a plate 45 secured to the lower portion of. the carriage 13, and this s ring tends to normally force the carriage-in tige direction of the grinding wheel 8.

The operation of the machine is comparatively simple. The grinding wheel 8 is adjustable vertically while the carriage 13 which supports the glass while it is being operated the arrangement of the aforesaid parts being such as to permit of beveling the glass at a different angle according to the desire of the workman. While the grinding wheel 8 rotatesvabout a horizontal axis the glass is rotated about a vertical axis while it is being operated upon by the grinding wheel and is firmly held in place during such operation by hereinbefore described'.

upon Ais adjustable longitudinally of the base, A

a peculiar clamping and supporting means carriage 13 in moving the work toward or llaving thus described the invention, what.

is claimed as new, is: v
